Abstract

An architecture that provides stimulus data and verifies the response of multiple electronic circuits substantially in parallel for optimized testing, debugging, or programmable configuration of the circuits. The architecture includes a test bus, a primary test controller connected to the bus, and a plurality of local test controllers connected to the bus, in which each local test controller is coupleable to a respective circuit. The primary test controller sends stimulus data and expected response data over the bus to the respective local test controllers to perform parallel testing, debugging or programmable configuration of the circuits. Each local test controller applies the stimulus data and verifies the circuit response against the expected response data. Further, each local test controller stores the result of the verification for later retrieval by the primary test controller.
